Extracted text: Ammonium hydrogen sulfide decomposes according to the following reaction: NH,HS(s)<>H,S(g) + NH;(g) a) 1 g NH4HS and the ammonia from a 500 cm3 container, which is at 0.530 atm and 250C, are introduced into a closed 2-liter container. Calculate the partial pressure of hydrogen sulfide at 2500C. b) For the decomposition of ammonium hydrogen sulfide to be 10%, calculate the amount of ammonia that must be subtracted or added to the mixture. Data: ArH° = 92,72 kJ/mol A,S° = 159,58 J/mol K Besult; a) 0,242 atm; b)0.124 mol
